restart after loss in service?

I just took a trip for the weekend and much of the area i travelled thru didnt have cell service. However I found that when my phone was in a cell service area it wasnt making calls. here is the scenario...
driving down the highway, my cell isnt finding a signal, it sets itself to the airplane setting & thus calls cant be made, my wife's curve has a signal & she's on the phone, so i turn the phone back on & try to make a call...it ends my calls before it rings. i try to wait to see if its a timing issue, 10 minutes lapses, wife still on phone, i try to make a call, no go.
i had to cut my phone off & cut it back on to get the phone to work?? it recognized a signal as i had 1 bar of signal reception on the tilt and my wife's curve had 2 bars. but it'd never start a call. i'd see that it said calling, 3-5 secs later it said call ended...
anyone have any idea as to why this would happen or why i'd be required to restart everytime i leave a cell service area & reenter one? any fixes? i searched for my title & found no results...

Are you on 3G or GSM when it fails? If it's on 3G, you could have that problem, try to switch to GSM only and see if it's better.

well as far as i know we're not getting 3g until may...but i do drive towards a 3g network, so it may have been switching over to 3g prior to driving into the back country?

i checked & the phone is actually set to gsm only already...so this cant be the issue. any other thoughts?

Wish I had an answer, but my phone does the same thing. I must reset the phone to get a signal

what rom are you on? the 162 htc/att rom? bcuz i know now i am having a problem i wasnt before. because there is a building downtown that doesnt get cell service in it, and i frequent that building. i never had the issue on my original tilt on the 158 (i believe) rom, but this rma came w/ 162 rom & now im having the issue in that bldg too. which goes to further prove its not the 3g network theory. its just a matter of losing signal & then getting signal back where i am experiencing the issue.
thanks for any help.

Today was day one with the new tilt and it didn't have the problem. However, my old one wasn't consistent one way or the other, either, so I'll have to give the new one some time.

(work for at&t) New phone will not fix this problem, nothin wrong w/ phone. U need to go to a local corp store and change the SIM and get someone who knows what they r doing so they put all of the SIM updates while plugged into the comp. OTA updates will never work w/o these initial updates.

I have an issue where i'm connected to the net (GPRS/hdspa) and occasionally i will lose the connection whislt the connection is still active..
No internet functions will work even when i reconnect
I have to then restart the phone to be able to use the internet again
Not the same issue but something similar

Same problem here. It is not possible to establish a 3G connection. If I set the BAND in the telephone Settings to GSM the connection is stable. If try to establish a 3g connection all further connection trys will fail.
I already changed my Kaiser, it did not help.
Update:
T-mobile will sent me a new sim card. Hope this will help...

Inabuilty for Simultaneous Voice and Data

Why is the Nexus One unable to do Simultaneous Voice and Data.
I have searched hi and low.
And yes i am in a 3G area and all that jazz.

I am in 3G.
I have no problems when putting my sim in my tp2. And talking while surfing.
And i am not the only one. No one has givein a reason as to why.

Uh..unless you changed you radio settings to "WCDMA only" you should be able to talk and surf.

It should work. I do it all the time, but it is network dependent.
In case it works on your TP2 i suggest you check your settings.

Hey big guy are you using a t-mobile nexus one on AT&T? Or AT&T N1 on T-mobile? That used to send all my calls to voicemail while I was on the intarwebs

Incorrect. "WCDMA only" is still UMTS/HSPA (3G/3.5G in consumer speak), therefore you still get voice/data at once. I can only conclude that you're under the assumption that UMTS/GSM work the same way EVDO/CDMA does. On an EVDO network, all data goes through the EVDO network, while voice stays on 1xCDMA, because EVDO is an addon to 1xCDMA.
UMTS and GSM are two completely incompatible technologies that only share GSM backend features and a SIM card. The circuits in the phone are separate, the antennas on the towers are separate. You're either completely on UMTS for voice and data (inc. both at the same time) or you're completely on GSM (for voice or data but not both at once. In fact, if you're locked on to a strong UMTS signal, the parts of your phone that handle GSM shut down for power conservation and only wake up when your signal drops to check to see if you'll get a superior signal over GSM. It will do this periodically, but won't stay active for long unless your UMTS is so bad that you won't be able to hold a call. THEN your phone powers up and maintains the GSM radio, while putting the UMTS radio on standby, only powering it up momentarily to look for a better signal.
The only time you have GSM and WCDMA/UMTS powered on at the same time is during hand-offs from one network to the other. That's why staying in areas where you bounce between the two kills your battery so quickly, the radio is drawing roughly twice as much juice as it normally does, plus it's computing which one will do the better job for the moment. Even then, at that time, the phone and its OS will be using only one of the networks at a time, and if it's UMTS, you'll be able to hold a call and surf the web.

TMO on TMO.
Attached are my settings.
I have this on every rom or radio i try.

Hey, sort of same thing just happened to me
in my case using GSM Auto (prl) or WCDMA prefered I can connect to HSDPA but GSM is in emergency calls only, weird.
but I can do both on GSM only (GPRS/EDGE)

Re-flashed to official release of 2.1 same thing.

i use voice and data on my nexus at the sme time every day. it just works. as long as you have a 3G symbol next to your reception bars, then it works.
i dont know what you could have done to break this. can you demonstrate to us what you are doing that is not "working"?

I am connected to 3G network. Call comes in. I can not browse on the internet. While i am on the call i go check settings and i have droped to GPRS. As soon as i hang up i go back to 3G (HSDPA)

Have you ever changed your build.prop file at all in the past? If so that's the problem. Change to hsxpa=2 to fix it.
If not then I have no clue.

I have no problem on my TP2.

I use it often too but today I was unable to it. Hopefully its because my area is being updated to hsdpa+

i think i have the same problem. 3G drops during voice call, doesn't connect during the call. reconnects after the call ends.
stock nexus one tmobile FRG83D

When you have bad reception, that's what happens. Normal and expected. During the call it won't re-negotiate 3G, only when the call ends.

Yeah, that is normal and it really sucks when you're on a long call. Once you lose 3G signal it's gone for good. I don't know if it's a network problem, or the phone, but it should be fixed.

HTC One M8 reception worse than M7

I just got my new M8 today. Did the update, activated it, did the profile & PRL update, etc.
I am constantly getting the message that I am roaming on data. It seems to go back and forth between roaming and not roaming. Even outside I only get 1 bar of LTE and the LTE signal is a good 10dBvm worse than my old M7. My M7 never switched to roaming in the same location.
Anyone else noticing worse reception on this phone than the old HTC One?

I'm having the same issue.
Sent from my 831C using Tapatalk

I was worried bout the same myself. In the office with the M7, I wan't able to get LTE, but luckily with the M8 I am able too. I would have your phone checked at a corporate Sprint Store to see if it's faulty

I had the same issue yesterday when I upgraded my radios to the new version (1.54). I was stuck in 3G roaming at my house which was normally low end LTE service before the upgrade. After flashing the radios I did a Profile and PRL update using WIFI, then restated my M8. After the restart I am back to having LTE coverage floating around -90-95 dBvm. I also notice that if LTE fails to connect swithing airplane mode On/Off helps as well as dialing *18 from the dialer. Hope it helps.

I already did the profile/prl updates, and my phone isn't stuck on 3G. It will go 3G roaming, then 3G on sprint, then LTE. Seems to not be able to make up its mind. On my old phone it would usually toggle between LTE and 3G in this area, but NEVER did it go roaming. Even when I'm on WIFI I still get the annoying roaming notification in the notification bar every 5 minutes.
I also noticed my WiFi download speed on wireless AC is significantly worse than my M7. I used to be able to get 70mpbs on a speed test, this phone won't even break 12mbps. When I first turned the phone on it would only work on WiFi for the first 3 seconds after connecting and then it would stop. I had to keep connecting and disconnecting to WiFi to limp the software update download along. After it updated it at least stays connected and working on WiFi, but a lot slower than my old M7.
This phone was purchased on a SWAC account so I'm not sure if a Sprint store (which is 40 minutes away for the nearest one) would swap it for me.

Moved to Q&A...all questions should be posted in Q&A.
Thank You,

HALP! Signal problem or defective phone?

I'm not very familiar with this. I've have data (4g lte) connection issues for a while now with my m8.so much so that I'm considering going back to Capts fastboot recovery file just to wipe everything and start over. I'm constantly in a 4G area, but can't get it unless I switch to airplane mode and back. Even then it's short-lived in multiple known 4g areas.
Anyway, tried updating prl. Get an error 1012. But when connected to my airave no problem. Just wondering if that's good to update while hooked up to airave cause I can't in a data area.
Thanks
Don't forget the thanks button!

Ok no one has said anything lol
I've been reading and trying to research my problem. I thought I saw a thread on this same issue but haven't found it yet (hard juggling wife kids work & Android).
Anyway I've spoke with sprint and I just don't trust them.
Been watching my signal on net monitor and everytime I connect to am ehrpd tower my phone tries to connect to lte but apparently didn't want to and jumps down to 3g. I can get lte but has to be a lte tower. Not real knowledgeable yet in this stuff but I'm trying.
Currently on Viper
Firmware 1.54.401.5
Prl 51100

I'm having similar symptoms. I upgraded this past Monday from a Samsung S3 that had good LTE and CDMA voice inside my home (Plano, TX) and my new M8 cannot maintain any stable connection on the voice or data sides. Even at my workplace, I can only get a weak LTE/Spark connection and no voice. I've already worked with several techs and support people at Sprint throughout the week and even exchanged to another new M8 with no better success. I believe it has to do with the Spark (which is actually one of the LTE-Advanced features) and the CSFB (Circuit-Switched Fall Back) that allows us voice on the old CDMA network until VoLTE to rolled out. I am frustrated enough to turn it back in and just go back to using my old S3.
FWIW...

I have no problem with the voice. This is where it seems many are having problems. I'm trying to figure out if this phone is supposed to behave this way with ehrpd towers.
Don't forget the thanks button!

I've mentioned in a different thread that LTE for me is mostly stable, but it does get a little wonky on me. For example, one day at work the LTE will be strong and solid and the following day it drops out intermittently and toggles 3g on.
Probably a sprint issue, not an m8 issue

I had the same prob with my first M8. Could not got 4g until I switched airplane mode off/on. Took it back withing 14 days and got a new one. This one gets 4g/LTE now but have had to switch airplane mode a couple times. Also, my airave does not like this phone. Sometimes it will give it full signal and then other times 4g will be showing and I have no signal and miss calls. I called airave support and the solution they gave me was to switch to cdma when at home.

This is a known issue with the M8. Some people have had success with HTC replacing the defective phone. http://forums.androidcentral.com/htc-one-m8/390449-sprint-signal-issues.html

Yep, defective phone
I had terrible connection problems after buying a brand new phone! Ex: No service, Dropped calls every minute, No LTE, 3G was rare. Basically it was not even a phone! I had to ship mine back to HTC. This was after hours at the Sprint store, and many customer service chats with HTC reps. I also had to unroot my phone which was a huge hassle considering I just found out how to root it. After getting a new one, works fine.
Don't let them tell you it is a service problem if you are having the same symptoms. THIS IS A HARDWARE PROBLEM and HTC needs to fix your phone. Hope this helps

wifi calling on marshmallow with nexus 6 on tmobile - anyone get it to work?

has anyone managed to get wifi calling to work on tmobile on marshmallow? i bought my phone directly from motorola and they claim that is part of the problem but looking at multiple other threads on tmo's support website, that isnt the issue as other people are able to get it to work

No problems using Cataclysm and elementalX kernel, at home it says "wifi calling" on the quick tiles and when on a call. Maybe try a different modem? Or if rooted try a different kernel.

its a marshmallow radio

I'm running stock MRA58R, no root, fresh from the factory images. T-Mobile WiFi calling works perfectly.

I'm stock rooted, and it works, but I wouldn't say it works well. I even have a CellSpot at home and it's a little wonky. It doesn't seem to hold it's connection (wifi calling connection that is, wifi itself is fine).
I was at a cabin this past weekend where there is no T-Mobile signal and wifi calling didn't work for MMS at all. I was able to send normal SMS texts and stuff, but MMS (group messages) didn't come through at all. I didn't get all the messages until I was back on the interstate on the way back home.
Part of the reason I upgraded to the N6 from the N5 was because of wifi calling and it doesn't work all that well to be honest. I've had many times, even at home (cell spot router), where MMS messages fail to send. Receiving seems to be just fine, but sending seems to be problematic.
I bought my N6 from Amazon back when they were $350 new a month to six weeks ago, whenever that was, so it wasn't from T-Mobile directly, but that's not supposed to matter.

did you get your phone directly from tmo or elsewhere?

ive now tried every different radio without luck, doiuble checked every single setting to ensure everything was appropriate
called tmobile several times - everything is correct on their end

Do you have a E911 address on your T-Mo account? If not, add it to the account, and then try.
What is the exact error message?

i do have it set
"turn off airplane mode or connect to a wireless network to make a call"
is the message
when i try to use wifi calling with airplane mode on and connected to any wireless network
when im on the cellular network, it only uses celluar network, no HD calls and no WIFI calls

WiFi calling is working for me, except whenever its enabled it slows the WiFi way down. I ended up just getting the 4G LTE cellspot for $25 so I have really good Band 4 LTE signal for calls and can keep the WiFi running at full speed.

Are you using the TMO router too? When I asked at the store about the LTE CellSpot, they said I would have to turn in my router, as you can only have one or the other.

I don't have the router. And I do believe you can only use one or the other.
I already have a nice router so that wasn't a problem.
I have been very happy with the LTE cellspot I get full LTE signal in a pretty big house.

Thanks for the quick response! My TMO router was a big improvement to my previous one, and I don't see any slowdown when using WiFi calling with it, so I guess I'll just stick with what I have.
